Answer: Associative Property of Addition

We basically have 2+x+y on each side. The difference is the use of parenthesis in different places. With addition, we can add in any order we want and that includes grouping terms as well. For example
(2+3)+5 = (5)+5 = 5+5 = 10
2+(3+5) = 2+(8) = 2+8 = 10

So that's why in general (2+x)+y = 2+(x+y) is true for all real numbers x and y.

The perimeter of the rectangular playing field is 320 yards. the length of the field is 4 yards less than triple the width. what
fgiga [73]
Let the width be X
Then the length is X + 70
The perimeter is the sum of all sides
There are 2 widths (left side and right side) and 2 lengths (top and bottom)
Perimeter = 2 * width + 2 * length
Perimeter = 2 * X + 2 * (X+70)
Perimeter: 2 X + 2 X + 140 = 380
4 X = 380-140
4 X = 240
X = 240 / 4
X = 60
Width = 60 - the smaller of two sides
Length = X + 70 = 60 + 70 = 130 - the larger of two sides


Check:
<span> 2 * 60 + 2 * 130 = 380 </span>
